Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Husqvarna's exact tolerances for the Inner Flange 130, ensuring proper blade clamping force and concentricity on the arbor.
- Direct Drop-In Replacement — Engineered to match the original mounting interface, allowing straightforward installation without modification to the blade guard or spindle assembly.
- Broad Wall Saw Compatibility — Confirmed fit for the WS400, WS482, WS440HF, and WS440 wall saws, covering both standard and high-frequency models in the WS series.
- Blade Stability Under Load — A correctly seated inner flange keeps the diamond blade running true during deep vertical and horizontal cuts, reducing vibration and protecting the blade segment bond.
- Safe Blade Retention — The inner flange is a critical component of the blade clamping system; using a genuine OEM part maintains the clamping geometry that prevents blade slippage during high-load cutting operations.
The inner flange is one half of the blade clamping assembly on a wall saw spindle, working together with the outer flange to clamp the diamond blade securely in place during operation. It locates against the spindle shoulder and transfers rotational force evenly across the blade's mounting bore, keeping the blade running concentrically and minimizing lateral runout. When the inner flange is worn, damaged, or out of specification, blade stability suffers — leading to uneven cuts, accelerated blade wear, and increased stress on the spindle bearings.
